  • Patent number: 8253107
    Abstract: A neutron image detection method is disclosed, which collects a fluorescent light generated by a neutron incident at a designated position interval in one-dimensional geometry and determines an incident position of the neutron by detecting the collected fluorescent light, in which the fluorescent light is detected by a photon counting method; a pulse signal generated by an individual output photon is extracted on the basis of a clock signal generated with the same time interval as the time width of the pulse signal generated by a single photon; a count-value distribution is obtained in terms of incident position as variable determined by a single neutron incident by counting the pulse signal output; and a neutron incident position is determined by calculating a median point on the basis of the obtained count-value distribution.
